Application filed September 28, 1918. Serial No. 256,046.

To all whom it may concern:

Be it known that I, WILLIAM J. NOBLE, a citizen of the United States,residing at Kearney, in the county of Buffalo and State of Nebraska,have invented certain new and useful Improvements in Demountable DrivingWheels for Motor-Oycles,.of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to an improved demountable driving wheel formotor cycles,

and has for its primary object to provide improvedmeans for easily andquickly assembling the wheel in the machine frame and operativelyconnecting the same to the driving sprocket and the brake drum, or removingsaid'wheel when necessary without disturbing the positions of thelatter elements.

'It is a more particular object of my invention to provide in a motorcycle, separate shafts upon: which'the wheel, the driving sprocket andthe brake drum are mounted, and means forqui'ckly coupling the wheelshaft to the sprocket and crank shafts, whereby the shafts are caused torotate as a unit. 1 j i It is also a further object ofmy invention toprovide a demountable wheel for motor cycles whichis relatively simplein its construction, strong and durable, and can be manufactured-atrelatively small cost.

With the above and other objects in view, the invention consists in-theimproved construction, combination and relative arrangementnoftheseveral parts as will be hereinafter "more: fully described,subsequently claimed andillustrated in the accompanying drawing in whichsimilar reference characters designate corresponding parts; throughoutthe several views,and where1n:-

Figure 1 is an elevation illustrating the preferred embodiment of theinvention; Fig. 2 is a'sectional view taken onthe line 22 ofFig. 1*; r

I Fig. 3 is a section taken on the line 3-3 of Fig.2; and

Fig. {lis a. fragmentaryerspective-view of oneof the coupling mem ers. 11

. .Refe-rring detail to the drawing, 5 designates the side-frame bars ofa motor cycle, to (which. thembearingsao are bolted or otherwiserigidly-rsecured. Short, inwardly projecting shafts 7 and? 8-respec-,tivfely arejournaled in these bearings. Upon the shaft. 7 the driving,sprocket? 9- is-keyed,

and upon the shaft 8 thebrake drum 10 is similarly secured. Upon theinner end of each of the shafts 7 and'8, adisk 11 is fixed, and each ofsaid disks is provided in its perlphery at spaced points with thedovetail mortises or recesses l2.

l3 designates the drive wheel shaft, upon which the drive wheel 14 iskeyed. To each endof this shaft, the disks 15 are fixed, said disksbeing complementary to the disks 11 and likewise each provided in itsperiphery with the spaced dove-tail recesses 16. The means for couplingthe disks 11 and 15 together at each end of the wheel shaft 13 isidentical, and therefore the detail descript on of one coupling meanswill suflice for both.

In the disk 15, suitably spaced, inwardly projecting guide pins 17 arefixed, upon which a metal ring or annulus 18 is loosely engaged formovement laterally toward or from the side face of the disk. To thecoupling ring 18, the spaced outwardly proserted through the registeringrecesses, the

beveled side edges of the lugs having wedging engagement with the sideedges of said recesses when the coupling ring 18 is closely engagedagainst the inner side face of the disk 15. l

. Each'of the coupling lugs 19 is provided in spaced relation to itsfree end andin the inner=facethere0f with a groove or channel 20. Thesechannels are adapted to receive the locking fingers or extensions 22,which project radially from a plate 21 mounted upon the outer side faceofthe disk 11. This plate is formed with a series of spaced arcuateslots 23, through which headed studs or pins 24:, fixed in the disk, areengaged. These studs limit the 'rotativemovement of the plate 21withrespectto the shaft or axis of the disk 11. The plate 21ispreferably formed with a suitable handle, indicated at 25, whereby itmay beshifted. In the movement of said plate in one direction, thefingers 22 are engaged in the grooves or channels" 20 in the ends of thelugs 19, the studs; 24 limiting suclr movement. The coupling lugs are,therefore, securely locked and held against longitudinal movement 111the recesses of the coupled disks 11 and 15. The plate 21 is providedwith an opening adapted to coincide with a threaded opening in the disk11 to receive a screw 26, whereby the plate 21 is held in its lockingposition and the possibility of the release of the coupling members,owing to casual shifting movement of the locking plate, due tovibration, thereby prevented. In this manner, it will be seen that theshaft of the motor vehicle wheel-may be easily, quickly and securelycoupled to the shafts 7 and 8, upon which the driving sprocket and thebrake drum are mounted so that all of said shafts willrotate as a unit.Then it is desired to remove the wheel 14, it is only necessary to firstremove the screws 26 and then shift the locking disks 21 so astodisengage the fingers 22 thereon from the grooves in the couplinglugs. The rings 18 are then forced inwardly upon the guide pins 17 andthe lugs 19 disengaged from the recesses in the disks 11. The shaft 13with the vehicle wheel la may then be bodily lifted and removed from themachine frame without disturbing the mounting or arrangement of thesprocket wheel and brake drum.

From the foregoing description, taken in connection with theaccompanying drawing, it is believed that the construction, manner ofuse, and several advantages of my invention will be clearly and fullyunderstood. The device provides means whereby the drive wheel of amotorcycle can be easily and quickly removed when repairs are necessaryand as readily replaced in position and coupled to the sprocket wheeland drum shafts. Thecoupling means, as above described, is exceedinglystrong and durable,

and capable of withstanding the severe strains incident to theapplication of the brake, such coupling means effectually preventing anypossibility of relative rotation of the shafts which would render thebrake inefiective. The several partsof the device as herein describedmay be readily produced at small cost and easily and quickly assembled.It will be apparent that the disks Hand 15 above referred to can be ofany desired size and a greater or less number of the coupling lugs 19provided than as herein indicated. The several other elements employedare likewise susceptible of many minor modifications in their form andrelative proportions, and I accordingly reserve the privilege ofadopting all such legitimate changes as may-be fairly embodied withinthe spirit and scope of the invention as claimed.
